Thanks Joel, what do I need to give to the km range values parameters
then ?

-km:1.00,0.00,0.00,60.00,1.00 ?

Sorry for not seeing this obvious.

Cheers

Philippe

PS: Joel, I have tested Namma, but it is not suited to my .ecs script
(or I did not find the way to achieve it), would you mind tell me if it
could be done with my .ecs ? If you are ok I will send you my script.
